Last night’s cold and clear skies made good flying conditions for Santa. I could barely sleep, all excited about what he was bringing me. But when I looked outside for my new truck, I just saw my dented old one. I was dissed by Santa again. But at least I’ve got a nice day ahead of me: fresh snow from the weekend, southwest winds blowing 15 to 30 mph (NW direction in Cooke City), and temperatures in the teens that will reach into the high twenties this afternoon under mostly sunny skies. Overall, high pressure dominates with no snowfall predicted in the next few days.

Snowfall continued through last night with 24 hour totals of 4-6 inches in the mountains around Bozeman, Big Sky and West Yellowstone.  Cooke City received over a foot.  Winds increased yesterday out of the west to southwest at 20-40 mph, but spiked last night with gusts near 60 mph. Cooke City still has strong northwest winds blowing 30-50 mph.  Today will become partly cloudy and temperatures will rise into the upper twenties by this afternoon. No new snow is expected and Santa should have good visibility as he makes his rounds to all those naughty and nice.

This latest round of moisture has been delivered on a northwest flow, which will likely persist through much of the day. By this afternoon, an additional 2-3 inches is possible in the mountains around Bozeman and Big Sky. The southern mountains should see an additional 1-2 inches.
